Hello All,
I'm using seven ATEN UC-232A USB-serial adapters on a 2.4.26 kernel and have found that data read from any of these devices it littered with NULs. For example, here's a sample from a Cisco router's boot sequence:
# cat /dev/usb/tts/1 > /tmp/o # vi /tmp/o [EMAIL PROTECTED] System Bootstrap, Version 12.1(3r)T2, RELEASE SOFTWARE (fc1)^M [EMAIL PROTECTED] (c) 2000 by cisco Systems, Inc.^M C2600 platform with [EMAIL PROTECTED] Kbytes of main memory ^M ^Mprogram load complete, entry point^@: 0x80008000, size: 0x8f6510 ^MSelf decompressing the image : [EMAIL PROTECTED]@[EMAIL PROTECTED]@[EMAIL PROTECTED]@[EMAIL PROTECTED]@[EMAIL PROTECTED]@[EMAIL PROTECTED]@[EMAIL PROTECTED]@[EMAIL PROTECTED]@[EMAIL PROTECTED]@[EMAIL PROTECTED]@[EMAIL PROTECTED]@[EMAIL PROTECTED] [EMAIL PROTECTED]@[EMAIL PROTECTED]@[EMAIL PROTECTED]@#^@
None of those NULs were sent by the router.
Is this a known issue? (list archive doesn't seem to indicate so)
Regards,
Ben
(Specifically, I'm running Debian kernel-image-2.4.26-1-686)
